If you are talking about "low" volume another option you could consider is using a waffle tray. At a previous company we made low volume high value flexi-rigids. Like you, no-one would buy volume on reels. Luckily we had our own machine shop and we m

We have been processing a 3 and 5 up flex array for nearly four years on pallets and have had a pretty steep learning curve. Make sure you have vacuum holes in your pallet for the screen printing process, also work with your support block vendor to

Panasonic Flexi-Cam is supposed to support different types of equipment (including third party). Not sure if it will support AX-72, if they don't, you could ask. I know they support a range of Universal Equipment. Back in the day, when PanaPRO woul
